Application filed January 13, 1912, Serial No. 671,842.

To all whom it may concern 1 Be it known that I, RICHARD E. MEYER, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in Folding Boxes, of which the following is a specification.

This invention relates to folding boxes adapted to be made from sheet-metal or paper board and the like, and it has for one of its objects the provision of an article of this character which is made from a blank the corners of which are folded inwardly and are adapted to have the marginal portions ofv the side and end portions folded over to preserve the box in its entirety in its proper form and condition.

Further objects of the invention will hereinafter appear and be particularly defined in the claim.

The invention has been clearly illustrated in the accompanying drawings in, which similar characters denote similar parts, in which:

Figure 1 illustrates the blank from which my improved box is made. Fig. 2 illustrates one side and one end wall of the blank folded together. Fig. 3 is a primary section on line 3, 3 of Fig. 2, on an enlarged scale. Fig. 4 is a view similar to Fig. 3 and illustrates a further step in the formation of the locking joint at the top edge of the box, and Fig. 5 shows the lock above re ferred to, complete.

Referring to the drawings, the blank from which my improved box is formed is illustrated in Fig. 1, in which the fold-lines are indicated by dotted lines and in which the central portion 10 constitutes the bottom of the box which also comprises the front and rear sides 11, 12 respectively and the end walls 13. The adjacent portions of the side and ends are connected by corner portions indicated at 14, adapted to be folded inward in the manner shown in Fig. 2 where it will be seen that the top edge of the corner fold 14 (broken away) is slightly higher than the top edge of the other part 14 of the fold. It willbe understood, of course, that the corner fold 14 in its entirety lies flatly against the box-end 13 which latter has a tab 13 so arranged that it may be folded over the top edge of the fold part 14' to complete the box at that particular point and to hold the several members together. The particular construction and organization of the fold 14 relative to the end member 13 of the box, is shown in its primary condition in Fig. 3 in which it will be seen that the top margin of the fold part 14 extends above the top edge of the fold parts 14, so that the former may be bent over to rest against the inner face of the box-side 13 as shown in Fig. 4, and thus form a crimp 0 whichlatter serves to reinforce and stiffen the structure along that line, it being understood that the extreme upper end or crimp edge of the member 14 will project upward beyond the crimp far enough to permit the tab 18 of the box end to be folded over the same as shown in Fig. 5. It is preferable before bending or crimping the part 14 to provide a small slit at the junction of the upper edge of the part 14 and the rear side of the box, whereby as the part 14 is bent it will not drag the rear wall of the box and thus distort the crimped portion of the fold. The crimping or bending of the fold part 14 is so slight however, that the rear wall 12 is not perceptibly distorted and even though it does draw the end of the wall inwardly this is an advantage in having a flanged lid easily fit upon the box. From this it follows that at this point the box end comprises three layers only, and it is on this particular point where differentiation is made from soce constructions of folding boxes used heretofore. The same corner construction (illustrated in Fig. 2) is applied to the remaining corners of the box, the particular feature residing in the fact, which is especially emphasized, that the intermediate fold-part 14 is less in height than the inner fold-part 14' which latter is, in turn, less in height than the box-end 13. Of course it is evident that when the tab 13' is folded into the position shown in Fig. 5, the entire construction becomes a fixture which preserves the box in its proper shape and form.

It will be noted that the rear side 12 of the box is provided with a series of slots 15 and cut-away portions 19, each of which is adapted to receive the hinge portions of a cover not shown.

I claim:

A folding box comprising a bottom, side and end walls connected therewith, corner folds foldable' into parallelism with the end walls of the box'and each comprising two plies, the one confronting the end wall of the inner ply being at a point below the being of less height than the inner ply tion thereof in the same plane as said inner whereby the'upper edge of the inner ply can ply. 0 be bent onto the upper edge of the outer ply In testimony whereof I affix my signature and against the end wall, the upper edge in the presence of two witnesses.
